I just started using an Ernie Ball 25K volume pedal as an expression pedal and it works with any preset that has been setup up already. But I am unable to do any new programming or remove any existing exp pedal settings. I've watched the Eventide video and noticed that when using the exp pedal, I am not seeing the corresponding effect module light flash, as in the video.
I'm running the latest version 3.5.0 
Is there a setting I might be missing?
